SPECIFICATION forming part of Letters Patent No. 608,829, dated August9, 1898.

Application filed March '12, 1 8 93- To aZZ whom it may concern.-

Be it known that we, DENNIS BRENNAN, JOHN It. W IRLEY, and EVERETT GOLD-THWAIT, citizens of the United States, residing at Elkhart, Indiana,have invented certain new and useful Improvements in Devices for BendingAngle-Bars, of which the follow- Our present invention relates to animproved device for straightening the angle plates or bars ofrail-joints; and the object of the invention is to provide a simple andofby means of which the angle-bars may be the bend and at the pointwhere they are used without necessitating their being carried to a shopor like repair-house.

The invention is illustrated in the accompanying drawings, in which- IFigure 1 is a plan view of the device a used in straightening the plate,showing a sufficient portion of a railroad-rail to illuselevation of thedevice, showing the rail in the fish-plate in the various positionsassumed become bent or distorted. Fig. 6 is a detail In the drawings therail is designated at 1 This an enlarged head 11", provided with holes11 for the reception of a suitable handle for While this form of poweris preferable, we do not desire to limit ourselves to The angle plate orbar to be straightened is shown at 1%, and in order to hold it spaced asuitable distance from the rail to permit the straighten itbearing-blocks 5, 6, and 7 are Serial N0. 673,623. (No model.)

employed. Of these the blocks 6 and 7 are counterparts of each other andare located one at each end of a connecting-rod 8, while receive andsupport the angle-bars in a num- 7 her of positions, according to thebent condi-' tion of the angle-plate to be straightened.

The forward end of the screw 11 is rounded and adapted to bear against arounded socket in a bearing-block 10. This bearing-block has three facesdifferently shaped to fit the faces of the angle-bar in as manypositions and has three rounded sockets in its three remaining sides forthe end of the screw, as before stated.

Referring more particularly to Fig. 2, in which the parts are shown inposition for bending the angle-plate, it will be observed that thebearing-blocksflG and 7 have notched or recessed portions or, andslightly-inclined forward edges b, the former offering seats for thehead or upper edge a of the angle-bar, while the latter serves tosupport the lower edge I). The central block 5 rises only to a fractionof the height of the blocks 6 and 7, as clearly shown in dotted lines,and does not extend out so far from the rail, so that when pressure isapplied to the central por tion of the under side of the angle-bar byscrew 11 and pressure-block 10 the base-flange of the angle-plate isfree to be forced in wardly. The upper edge, however, of thebearing-block 5 is inclined, and as pressure is applied to the plate,forcing the portion a into the seats a and bending it in at the center,as before described, the inclined surface of the block 5 tends to liftthe central portion of the edge a slightly.

In Fig. 3 we have shown the angle-bar in another position, adapted to bestraightened to remove a bend of a different shape. In this it will beseen that the base of the angle bar or plate rests against seats orhearing faces 0 and c, the central block 5 not being necessary in thisposition and not contacting with the surface of the angle-bar. It willalso be observed that the block 10 has been shifted to bring itscorresponding side in contact with the upper edge of the angle-bar.

In Fig. 4 the angle-plate is shown in still another position, in whichit will be observed that the upper edge of the angle-bar, which is hereshown upside down, rests against shoulders d of the blocks 6 and 7.

For holding the angle-plate in still another position we find itdesirable to provide additional bearing blocks 13, having faces 6,adapted to abut against the inner face angleplate in the position shownin Fig. 5. These may or may not be connected, as desired, and while Weprefer to place them against the this respect.

From the foregoing description it will be readily apparent that aportable and extremely advantageous device isprovidcd. By reason of thusutilizing the rail as a part of the device when in operation the numberof parts to be carried around are greatly reduced and the Weightdecreased to a degree which renders it possible for the workman tocarryit easily from place to place. The anof use without the necessity ofsending them to the repair-shops.

It will be understood that while we have illustrated and described theinvention in connection with the ordinary rail and fish-plate, We do notlimit ourselves to the particular form of the rail and fish-plate, asthe invention is equally adapted to rails and fish-plates of any form.

Having thus described our invention, what we claim is 1. A device forbending or straightening railroad angle-plates comprising the clamptially as described.

2. A device for bending or straightening angle bars or plates comprisingthe clamp adapted to engage the rail, the connected bearing-blocksadapted to rest against the rail and having surfaces designed to sustainthe angle-plate, and means for applying pressure to the unsustainedportion of said an gleplate, substantially as described.

3. A device for straightening or bending angle-plates comprising theclamp adapted to engage the rail, the bearing-blocks adapted to abutagainst the rail and having a plurality of sustaining-surfaces adaptedto sustain the angle-plate in a plurality of positions, and

means for applying pressure to the unsustained portion of saidangle-plate, substan- ;tially as described. blocks 6 and 7 we do notlimit ourselves in 4. A device for straightening or bending angle-platescomprising the clamp adapted to 'Eengage the rail, the central and endblocks adapted to abut against the rail, bearing-surfaces on said endblocks adapted to sustain the ends of the angle-plates, an incline onsaid central block designed to contact with the 3 under edge or face ofthe plate being straightened, and means for applying pressure to the 5central portion of the angle-plate, substanitially as described.

gle-bars can thus be straightened at the point 5.
